It doesn't seem worthwhile to have bt_matchfinder_get_matches() return
the best_len separately anymore, especially since it doesn't work as
expected due to it not handling length 3 matches.
A lot of the internal library headers don't have include guards because
they aren't needed. It might look like a bug, though, and it doesn't
hurt to add them. So do this.
Update https://github.com/ebiggers/libdeflate/issues/117
Remove the ability of matchfinder_init() and matchfinder_rebase() to
fail due to the matchfinder memory size being misaligned. Instead,
require that the size always be 128-byte aligned -- which is already the
case. Also, make the matchfinder memory always be 32-byte aligned --
which doesn't really have any downside.
I've decided to simplify and standardize the licensing status for the
library by using the MIT license instead of CC0 (a.k.a. "public
domain"). This eliminates the somewhat controversial 4(a) clause in
CC0, and, for this and other reasons, should (somewhat ironically) make
it easier for some people to use and contribute to the project.
Note: copyright will apply to new changes and to new versions of the
work as a whole. Of course, versions previously released as public
domain remain public domain where legally recognized.
